I started accumulating Qantas points and currently have about 180k. My goal is to fly at least once on First Class on a long haul flight from Sydney. Preferably to any US or European destination that allows to use Qantas points directly or via any other affiliated airline. Flexible on the destination city as we can plan the holiday starting from the destination we choose. We are a family of 4 with 2 adults and 2 kids. How far off am I in achieving my goal? Any information on how much point I need would be great for both First Class and Business Class. And what is the process in redeeming tickets? Do I have to buy Economy tickets and then upgrade or use points entirely to buy the First Class tickets? What other charges will be there when redeeming points like fuel surcharge and tax that you have to pay by cash?
Thanks in advance for your help!
